Two commonly used techniques to speed-up these types of...

    Encouraging Information Security Behaviors in Organizations: Role of Penalties, Pressures and Perceived Effectiveness

    Secure management of information systems is crucially important in information intensive organizations. Although most organizations have long been using security technologies, it is well known that technology tools alone are not sufficient. Thus, the area of end-user security behaviors in organizations has gained an increased attention. In information security observing...

    New Advances in Polymer/ Layered Silicate Nanocomposites

    This review discusses some recent advances in polymer silicate Nan composites. In particular, we highlight the properties of specific Nan composites while emphasizing the lack of properties trade-offs in these systems. The paper also presents in detail the work on the structure and dynamics of the polymer/ nanofiller interface and...

    An fMRI Study of Semantic Processing in Men With Schizophrenia

    As a means toward understanding the neural bases of schizophrenic thought disturbance, we examined brain activation patterns in response to semantically and superficially encoded words in patients with schizophrenia. Nine male schizophrenic and 9 male control subjects were tested in a visual levels of processing (LOP) task first outside the...

    Volumetric Quantification of Brain Swelling After Hypobaric Hypoxia Exposure

    Conventional qualitative interpretation of two-dimensional cross-sectional MR images gives information about the localization and extension of edematous tissue in patients with brain edema. Changes in adjacent brain slices allow an approximate evaluation of the brain volume. Other approaches in characterization of brain edema are T2 mapping, diffusion weighted imaging, or...
